“…Specifi cally, our experiments with composition SM20 at 1300°C and log fO 2 of -3.4 (SP130813-3 and SP180213-5) resulted in partition coeffi cients that are consistent with those reported by Klemme et al (2005) for their equivalent experiment RT10-20, attesting for attainment of equilibrium. We note, however, that there is a systematic change in partitioning coeffi cients calculated for experiments with composition SM20 as a function of oxygen fugacity (Fig.…”

“…All monovalent cations (Na, Ba, K) are highly incompatible in rutile, and their partition coefficients should be seen as maximum due to the potential contamination of rutile LA-ICP-MS analyses with melt inclusions. The HFSEs are all compatible in rutile, with partition coefficients for Zr (1.1-7.6), Hf (1.4-10.7), Nb (7.4-90) and showing a range that is in agreement with previous experimental studies (see Figure 1 in Klemme et al 2005). The absolute values, however, vary quite significantly with melt composition.…”

“…We did not observe, however, any systematic difference in HFSEs partition coefficients determined for experiments with compositions SKHDAN1a, b and c. In other words, the type of trace element doping appears to have no effect on HFSE incorporation into rutile. Finally, as previously reported by Klemme et al (2005), (D = 10 -5 -10 -3 ) is at least 2 orders of magnitude more incompatible in rutile than (D = 0.12 -1.1).…”

“…We studied three compositions (SKHDAN1, SKHDRH1 and SM20), selected from the work of Klemme et al 2005, which are known to equilibrate rutile and silicate melt at atmospheric pressure (1 bar) between 1250 and 1300°C ( vertically with temperature variability within ±2°C (Fig. 3).…”

Subduction zone or arc magmas are known to display a characteristic depletion of High Field Strength Elements (HFSE) relative to other similarly incompatible elements, which can be attributed to the presence of the accessory mineral rutile (TiO 2 ) in the residual slab. Here we show that the partitioning behavior of vanadium between rutile and silicate melt varies from incompatible (~0.1) to compatible (~18) as a function of oxygen fugacity. We also confirm that the HFSE are compatible in rutile, with D(Ta) > D(Nb) >> (D(Hf) >/~ D(Zr), but that the level of compatibility is strongly dependent on melt composition, with partition coefficients increasing about one order of magnitude with increasing melt polymerization (or decreasing basicity). Our partitioning results also indicate that residual rutile may fractionate U from Th due to the contrasting (over 2 orders of magnitude) partitioning between these two elements. We confirm that, in addition to the HFSE, Cr, Cu, Zn and W are compatible in rutile at all oxygen fugacity conditions.

Volatile and stable isotope data provide tests of mantle processes that give rise to mantle heterogeneity. New data on enriched mid‐oceanic ridge basalts (MORB) show a diversity of enriched components. Pacific PREMA‐type basalts (H2O/Ce = 215 ± 30, δDSMOW = −45 ± 5 ‰) are similar to those in the northern Atlantic (H2O/Ce = 220 ± 30; δDSMOW = −30 to −40 ‰). Basalts with EM‐type signatures have regionally variable volatile compositions. Northern Atlantic EM‐type basalts are wetter (H2O/Ce = 330 ± 30) and have isotopically heavier hydrogen (δDSMOW = −57 ± 5 ‰) than northern Atlantic MORB. Southern Atlantic EM‐type basalts are damp (H2O/Ce = 120 ± 10) with intermediate δDSMOW (−68 ± 2 ‰), similar to δDSMOW for Pacific MORB. Northern Pacific EM‐type basalts are dry (H2O/Ce = 110 ± 20) and isotopically light (δDSMOW = −94 ± 3 ‰). A multistage metasomatic and melting model accounts for the origin of the enriched components by extending the subduction factory concept down through the mantle transition zone, with slab temperature a key variable. Volatiles and their stable isotopes are decoupled from lithophile elements, reflecting primary dehydration of the slab followed by secondary rehydration, infiltration, and re‐equilibration by fluids derived from dehydrating subcrustal hydrous phases (e.g., antigorite) in cooler, deeper parts of the slab. Enriched mantle sources form by addition of <1% carbonated eclogite ± sediment‐derived C‐O‐H‐Cl fluids to depleted mantle at 180–280 km (EM) or within the transition zone (PREMA).

Geodynamics of paleo‐Pacific plate subduction constrained by the source lithologies of Late Mesozoic basalts in southeastern China

Widespread Late Mesozoic volcanic magmatism in southeastern China is generally thought to represent products in response to the subduction of paleo‐Pacific plate; however, it remains unclear when this process began to affect the mantle and the related magmatism. Here we present a systematic study on the source lithology of Late Mesozoic basalts in this area to highlight a link between lithological variations of mantle and subduction process of paleo‐Pacific plate. Late Mesozoic basalts can be subdivided into four groups based on their erupted ages: 178~172 Ma, approximately 150 Ma, 137~123 Ma, and 109~64 Ma. The primary source lithology of these rocks is pyroxenite rather than peridotite, and this mafic lithology can be formed by either ancient or young recycled crustal components. Notably, the source lithology of the approximately 150 Ma and 137~123 Ma basalts is primarily SiO2‐rich pyroxenite, and the former is carbonated. The discovery of carbonated, SiO2‐rich pyroxenite reflects the influence of a recently recycling event in the mantle. The subduction of paleo‐Pacific plate is the most appropriate candidate and can be responsible for the mantle‐derived magmatism after approximately 150 Ma in southeastern China. Therefore, we suggest a paleo‐Pacific slab rollback with increased dip angle as a possible model to control the lithological variations of Late Mesozoic mantle beneath southeastern China.
